Monitoring equipment authentication method and device

Abstract

The embodiment of the invention provides a monitoring device authentication method and apparatus. The method comprises the following steps: a switch generates a random code, encrypts the random code by a public key of a monitoring device to obtain first encryption contents, and sends the first encryption contents to the monitoring device; the monitoring device decrypts the first encryption contents via a private key of the monitoring device to obtain the random code; the monitoring device encrypts the random code and feature information of the monitoring device by the public key of the switch to obtain second encryption contents, and sends the second encryption contents to the switch; and the switch decrypts the second encryption contents by the private key of the switch to obtain the random code and the feature information, judges whether the random code is generated by the switch, and executes a corresponding preset operation on the feature information according to a judgment result. By adoption of the monitoring device authentication method and apparatus, the monitoring device authentication management work become simpler, the information leakage risk is smaller, and the safety authentication of the monitoring device can be rapidly completed.

Description

technical field [0001] The invention relates to the technical field of security authentication of monitoring equipment, in particular to a method and device for monitoring equipment. Background technique [0002] In order to make the monitoring network cover the target monitoring area (for example, parks, underground parking garages, etc.) Accessing the monitoring network by replacing monitoring equipment threatens the security of the entire monitoring network. Therefore, it is very necessary to carry out security certification on monitoring equipment. In the prior art, access control and authentication protocols (for example, 802.1x) are generally used to perform security authentication on monitoring devices connected to the network. However, the above security authentication methods have the disadvantages of complex password management and easy information disclosure. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior ...
